[0031] In order to facilitate understanding of the present invention, several embodiments of the present invention are provided below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] See also Figures 1 to 8, is a rainproof tarpaulin carriage according to an embodiment of the present invention, comprising a carriage body 100, a rolling mechanism 200, and a traction mechanism 300.

[0033] A lifting limit portion and a sliding limit portion are provided on the left and right side walls of the body 100. The winding mechanism 200 includes a driving assembly, a roller 220 and a transmission assembly 230 arranged on the body 100. A rainproof tarpaulin 240 is wound on the roller 220. The driving assembly is connected to the transmission assembly 230. The transmission assembly 230 is connected to the roller 220 to drive the roller 220 to rotate. The forward and reverse rotation of the roller 220 can realize the winding and unwinding operation of the rainproof tarpaulin 240.

[0034] The traction mechanism 300 includes two rods 310 and a sliding support component 320 arranged side by side on the top of the car body 100. Optionally, the two rods 310 are symmetrically placed along the central axis of the car body 100 in the width direction, and a sliding portion is provided at the end of the rod 310 close to the side wall of the car body 100, and a connecting portion for fixing the extended end of the rainproof tarpaulin 240 rolled up on the roller 220 is provided in the middle of the rod 310, so that when the rod 310 moves toward the rear of the car body 100, the rainproof tarpaulin 240 can be gradually unfolded from the roller 220, or the roller 220 can be convenient for the rolling operation. In addition, the end of the rod 310 close to the side wall of the car body 100 is hinged to the sliding support component 320, and the transmission assembly 230 is connected to the sliding support component 320 in a transmission manner so that the sliding support component 320 can move horizontally relative to the sliding limiter, so as to achieve the effect of the rainproof tarpaulin 240 shielding the top of the car body 100.

[0035] When the sliding part on the rod 310 slides relative to the lifting limit part along the length direction of the car body 100, the vertical height of the sliding part relative to the sliding limit part changes, so that the rainproof tarpaulin 240 can always keep its front and back in an inclined state during the process of being rolled up and unrolled, so that rainwater is not easy to adhere to its surface. In addition, when the sliding part moves to the rear of the car body 100 relative to the lifting limit part, the rod 310 will gradually deflect upward around the sliding support component 320 at this time, and the middle part of the cloth surface of the rainproof tarpaulin 240 will bulge upward, so that its cloth surface is inclined from the middle to the left and right sides, which is conducive to the discharge of rainwater.

[0036] The connection portion can fix the rainproof tarpaulin 240 and pull the rainproof tarpaulin 240 when the rod 310 deflects up and down around the sliding support component 320.

[0037] In some embodiments, Figure 1 , Figure 3 as well as Figure 6As shown, optionally, the lifting limit portion is a first groove 110 arranged at the top of the left and right side walls of the carriage 100, the bottom wall of the first groove 110 is inclined and the bottom wall on the side away from the winding mechanism 200 is higher than the bottom wall on the other side, and the sliding portion is a protrusion 311 arranged at the end of the rod 310, and the bottom of the protrusion 311 is arc-shaped and presses against the bottom wall of the first groove 110.

[0038] The bottom of the protrusion 311 is pressed against the bottom wall of the first groove 110. Since the bottom wall of the first groove 110 is at an inclined angle, during the process of the sliding support component 320 moving horizontally to the rear of the car body 100 relative to the sliding limit portion, the arc-shaped bottom of the protrusion 311 is gradually lifted upward by the bottom wall of the first groove 110. At the same time, since the end of the rod 310 close to the side wall of the car body 100 is hinged to the sliding support component 320, the protrusion 311 pushes the end of the rod 310 upward, and the rod 310 deflects upward around the hinge, thereby causing the middle part of the cloth surface of the rainproof tarpaulin 240 to bulge upward, so that rainwater is not easy to stay on the front surface of the rainproof tarpaulin, thereby achieving the purpose of reducing rainwater residue.

[0039] In some embodiments, Figure 3 , Figure 6 as well as Figure 7 As shown, the sliding limit portion is a second groove 120 opened outwardly and arranged on the left and right side walls of the compartment 100, and the transmission assembly 230 includes: a first gear 231, a second gear 232, and a flexible transmission member.

[0040] Specifically, a mounting plate 130 is respectively provided on the left and right side walls of the compartment 100, the central axis of the roller 220 is rotatably connected between the two mounting plates 130, the first gear 232 is coaxially connected to the central axis of the roller 220, the second gear 232 is rotatably connected to the mounting plate 130 and meshes with the first gear 232, when the central axis of the roller 220 is driven to rotate, the first gear 232 also rotates, thereby driving the second gear 232 meshed therewith to rotate.

[0041] Among them, the flexible transmission component includes a rotating wheel 233 and a flexible member 234 that cooperate with each other. The rotating wheel 233 is rotatably connected in the second groove 120, and the flexible member 234 is transmission-connected to the sliding support component 320 to drive the sliding support component 320 to move horizontally relative to the second groove 120.

[0042] In some embodiments, Figure 2 , Figure 4 as well as Figure 6As shown, the sliding support component 320 includes: a limit plate 321, a transmission block 322, and a support plate 323. The limit plate 321 is fixedly connected to the compartment 100 and blocks the opening of the second groove 120. The limit plate 321 is penetrated by a slide groove 324 which is flush with the second groove 120. The transmission block 322 is transmission-connected to the flexible member 234, and its size is larger than that of the slide groove 324 so that it is limited in the second groove 120. The transmission block 322 is provided with a support portion and extends outward through the slide groove 324. The support portion is pressed against the edge of the slide groove 324. The support plate 323 is provided on the outer side of the limit plate 321 and its size is larger than that of the slide groove 324. The support plate 323 is fixedly connected to the support portion and the upper part of the support plate 323 is hinged to the end of the rod 310.

[0043] Optionally, the flexible member 234 is a chain, and the corresponding rotating wheel 233 is a sprocket. The sprocket is provided with two rotating shafts respectively arranged on both sides of the inner bottom wall of the second groove 120. The chain can drive the transmission block 322 to move in the second groove 120 during the rotation process. The chain and the transmission block 322 can be connected together by fasteners. Since the support portion on the transmission block 322 passes through the slide slot 324 and presses on the edge of the slide slot 324, the support plate 323 can also move along the extension direction of the slide slot 324.

[0044] Optionally, the flexible member 234 is a belt, and the corresponding rotating wheel 233 is a pulley. The pulley is provided with two rotating shafts respectively arranged on the bottom wall in the second groove 120. The pulley can drive the transmission block 322 to move in the second groove 120 during rotation. A clamping groove can be arranged on the belt to limit the two sides of the transmission block 322, and the clamping groove can push the transmission block 322 to move when the belt moves. Since the support portion on the transmission block 322 passes through the slide groove 324 and presses on the edge of the slide groove 324, the support plate 323 can also move along the extension direction of the slide groove 324.

[0045] In some embodiments, Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the rainproof tarpaulin carriage further includes a wiping mechanism 400 , and the wiping mechanism 400 includes: an articulated frame 410 , a roller shaft 420 , a synchronous transmission assembly 430 , and a water removal assembly 440 .

[0046] Among them, there are two articulated frames 410 arranged relatively to each other, both of which are hinged on the car body 100 through torsion springs, the roller shaft 420 is rotatably connected to the articulated frame 410, the driving component is transmission-connected to the synchronous transmission component 430, and the synchronous transmission component 430 is transmission-connected to the roller shaft 420 to drive the roller shaft 420 to rotate. In this way, when the driving component drives the roller 220 to rotate, the roller shaft 420 can also be driven to rotate through the synchronous transmission component 430.

[0047] The water removal assembly 440 includes a flexible water absorbing member 441 and an extrusion member 442 wound and fixed on the surface of the roller 420 . The flexible water absorbing member 441 contacts the rainproof tarpaulin 240 on the roller 420 , and the extrusion member 442 is fixedly connected to the two hinged frames 410 to press the flexible water absorbing member 441 .

[0048] Optionally, the flexible water-absorbing member 421 is a water-absorbing cotton, and the extrusion member 422 is a pressing plate. When the rainproof tarpaulin 240 is rolled up, the rod 310 moves to reset, and the driving assembly transmits the force to the synchronous transmission assembly 430, thereby causing the roller 420 to reverse, thereby driving the water-absorbing cotton to rotate to wipe the surface of the rainproof tarpaulin 240. At the same time, the water absorbed by the water-absorbing cotton rotates and is squeezed out by the pressing plate and falls off, thereby achieving the effect of reducing the water adhering to the surface of the rainproof tarpaulin 240 after the rainproof tarpaulin 240 is rolled up. In addition, since the hinged frame 410 is hinged to the car body 100 by a torsion spring, the position of the roller 420 can change with the thickness of the rainproof tarpaulin 240 wound on the roller 220, and when the water-absorbing cotton on the roller 420 is ensured to be normally close to the surface of the rainproof tarpaulin 240, the roller 420 will not have a significant impact on the rotation of the roller 220.

[0049] In some embodiments, Figure 3 and Figure 4 As shown, the synchronous transmission assembly 430 includes: a support frame 431 and a transmission shaft 432. The support frame 431 is fixedly connected to the compartment 100, the transmission shaft 432 is rotatably connected to the support frame 431, a transmission member is fixedly connected to the transmission shaft 432, the driving assembly is transmission-connected to the transmission member 433 to drive the transmission shaft 432 to rotate, and the transmission shaft 432 is transmission-connected to the roller shaft 420 to drive the roller shaft 420 to rotate.

[0050] In some embodiments, Figures 1 to 3 As shown, the driving component is a motor 210 fixedly connected to the car body 100, and the transmission member is a roller 433. The output shaft of the motor 210 is rollingly connected to the roller 433 through a belt 211. In this way, when the motor 210 drives the belt to rotate, the roller 433 will also rotate, thereby driving the transmission shaft 432 to rotate.

[0051] In some embodiments, Figures 4 to 7 As shown, the rainproof tarpaulin carriage also includes a vibration mechanism 500, which includes: an airflow dynamic member 510 and an eccentric rotating member. The airflow dynamic member 510 is rotatably connected to the sliding portion. When the airflow acts on the airflow dynamic member 510, the airflow dynamic member 510 can provide a torque. The eccentric rotating member is fixedly connected to the airflow dynamic member 510. When the torque acts on the eccentric rotating member, the eccentric rotating member will rotate relative to the sliding portion to generate vibration.

[0052] In some embodiments, Figure 6 As shown, the sliding portion is provided with a through hole 312 , the airflow power component 510 includes a rotating shaft 511 passing through the through hole 312 , a fan blade 512 fixed to one end of the rotating shaft 511 , and the eccentric rotating component is a semicircular eccentric counterweight block 520 fixedly connected to the other end of the rotating shaft 511 .

[0053] During the driving process of the vehicle, the airflow will drive the fan blades 512 to rotate rapidly, and the fan blades 512 will drive the rotating shaft 511 to rotate, and then the rotating shaft 511 will drive the eccentric counterweight 520 to rotate. Since the eccentric counterweight 520 is a semicircular structure and the eccentric counterweight 520 is located above the sliding part, the center of gravity of the eccentric counterweight 520 will change continuously during the rotation, thereby driving the rod 310 to vibrate. The vibration of the rod 310 drives the rainproof tarpaulin 240 to vibrate, so that the rainwater adhered to the rainproof tarpaulin 240 slides off the surface of the rainproof tarpaulin 240 more quickly. In addition, after the rain stops and the weather clears up, the rainproof tarpaulin 240 can also be vibrated by the vibration mechanism 500. Since the vibration can accelerate the process of water molecules on the surface of the tarpaulin to diffuse into the air, the speed of evaporation of water on the surface of the rainproof tarpaulin 240 can be accelerated to reduce the residual water.

[0054] In some embodiments, Figure 7 and Figure 8 As shown, the connecting part includes: a sliding cavity 331, a slider 332, and an elastic member 333. The sliding cavity 311 is arranged inside the rod 310. The sliding cavity 311 is provided with a strip-shaped connecting port (not shown in the drawings) on the side facing the winding mechanism 200. The rainproof tarpaulin 240 is partially slid from the slider 332 into the sliding cavity 331 and is fixedly connected to a part of the rainproof tarpaulin 240 close to the side wall of the car body 100. The two ends of the elastic member 333 are respectively fixedly connected to the end of the sliding cavity 331 close to the side wall of the car body 100 and one end of the slider 332.

[0055] Specifically, the elastic member 333 is a spring. It is understandable that the elastic member 333 may also be other elastic devices or parts with similar functions, such as an elastic sheet.

[0056] When the rod 310 is deflected, the slider 332 inside the sliding cavity 331 will slide to different positions according to the different deflection angles of the rod 310. When the rod 310 is deflected upward, the slider 332 will move toward the deflected end of the rod 310, thereby stretching the elastic member 333, so that the slider 332 always pulls the rainproof tarpaulin 240. The middle part of the rainproof tarpaulin 240 will therefore bulge upward, causing rainwater to fall on the surface of the rainproof tarpaulin 240 and flow out to both sides thereof, thereby achieving the effect of reducing the amount of residual moisture on the surface of the rainproof tarpaulin 240.
